So I've been reading for the last months about training zones and how to use them. But haven't really sticked to them. Just getting data around my workouts but following pacing. Mostly because I wanted to get an effort test to really know my top hr, but haven't been able to.
I've got a Garmin watch who calculated my zones following the partitioning of 50/60/70/80/90% zones.
Recently, an experienced friend gave me a different set of zones based on my resting HR and my age (25). They seemed very off from my previous so I wrote them down to find some kind of relation between them.
You can see more detail on this image but as the two right-most columns say, the intervals seem equally spread from Z1 through Z5, just a little more narrow.
e.g. Using a max HR of 195, old Z3 spans 137-156bpm (70-80%) with the interval length of 19bpm (156-137) but, new Z3 spans 154-167bpm (79%-86%) with the interval length of 13 (167-154).
Questions are:
- Is there some source that describes that Z1 should start from 50% or that it may start from 64% to achieve different objectives?
- Is the effort test really required to get my zones accurate? Or is the good ol' 220-age formula enough?
